Watermist (micromist) suppression systems produce a fine mist to extinguish fires quickly with very little residual water. Watermist provides a safe fire protection alternative for occupied spaces and high valued assets, such as machinery spaces, compartmentalized gas turbine generators, and many more. It is a safe, non-toxic, environmentally friendly extinguishing agent. Watermist uses a single fluid, intermediate pressure system, eliminating high installation costs associated with redundant piping networks and high pressure piping and fittings.
Watermist systems extinguish a fire by cooling due to droplet vaporization, oxygen displacement due to water expanding to steam, cooling the fuel surface, and washing out the products of combustion. The standard for watermist systems is NFPA 750.
Starfire Systems installs the Victaulic Vortex 500, 1000, and 1500 Hybrid Nitrogen-Water Suppression Systems. The average Victaulic Vortex droplet size is less than 10 microns, and the minimal amount of water released per emitter - as little as one gallon per minute - virtually eliminates any wetting in a space. Traditional sprinklers typically release more than 25 gallons of water per minute per sprinkler, or 96% more than the Victaulic Vortex system. In addition, high-pressure water mist systems release approximately 8 gallons of water per nozzle per minute, or 88% more than the Victaulic Vortex system.
Unlike other combined agent systems, the Victaulic Vortex hybrid system utilizes both nitrogen and water as complementary extinguishing agents. For smaller fires, the nitrogen is the primary extinguishing agent, reducing the oxygen level in the space to a breathable level, where combustion cannot be sustained. In larger fires, the water mist is more effective, cooling the fire by absorbing the heat and reducing the available oxygen. In fact, the heat-absorbing water droplet surface area is 90 times greater than that of any standard sprinkler system, providing maximum heat absorption efficiency.
Other benefits include:
Self contained, no additional piping
Fast, easy installation; no field calculation
Nearly zero wetting of protected areas; no need for costly clean up or equipment replacement
Green design that is safe for the environment and personnel
Quick system recharge; minimal facility downtime
No need for assurance of tight room integrity
